-This is a budget no-name Arduino UNO SMD clone with an CH340G USB interface rather than an ATmega16U2, and a ceramic resonator instead of the more precise and stable 16MHz crystal oscillator.  My example had a very crookedly mounted USB-B socket, and when I tried to resolder it flat onto the board it shorted something, disabling the USB port - so had to undo my fix :-(, and put up with it pressing on the underside of any Arduino shield mounted above.+This is a budget no-name Arduino Uno SMD clone with an CH340G USB interface rather than an ATmega16U2.  I also note both the genuine Arduino Uno SMD and this one use a ceramic resonator instead of a more precise and stable 16MHz crystal oscillator.  My example had a very crookedly mounted USB-B socket, and when I tried to resolder it flat onto the board it shorted something, disabling the USB port - so had to undo my fix :-(, and put up with it pressing on the underside of any Arduino shield mounted above.
  
 So a cheap Arduino Uno clone for applications not requiring precise timing or expectations of longevity :-). So a cheap Arduino Uno clone for applications not requiring precise timing or expectations of longevity :-).
